What makes Nucleus Mcp different from other context tools?
It is file-based (plain JSON + markdown), uses no embeddings, and has no vendor lock-in. All AI tools that support MCP share the same `.brain` folder.

Nucleus Mcp is an MCP server that provides a portable decision log (.brain folder) for AI coding tools. It stores decisions, policies, and plans in plain JSON and markdown files, giving Claude Code, Cursor, and Codex persistent memory across sessions without vendor lock-in.
Install via pip install nucleus-mcp or npx -y nucleus-mcp, then run nucleus init --recipe founder to auto-configure your MCP client. Add the remote server at https://relay.nucleusos.dev/mcp for no-install use with ChatGPT, Claude, or Perplexity.
It is file-based (plain JSON + markdown), uses no embeddings, and has no vendor lock-in. All AI tools that support MCP share the same `.brain` folder.
You can run it via Python (pip install) or Node.js (npx -y nucleus-mcp). No Python environment is needed if using npx.
Data lives locally in a `.brain` directory, discovered automatically by environment variable, walking up from the current working directory, or falling back to `$HOME/.nucleus/brain`.
Yes, anonymous aggregate usage statistics (command name, duration, error type, versions, OS) are collected, but no engram content, file paths, prompts, API keys, or PII. Telemetry can be disabled with `nucleus config --no-telemetry`.
The free MIT version includes all 13 tools, 10 resources, 3 prompts, persistent memory, governance, and audit trails. Nucleus Pro ($19/month) adds signed audit reports, full compliance exports, and priority issue support.
GoBuy gives AI agents marketplace-evidence trust scores. One call returns a 0–100 Evidence Score with observed/missing signals, freshness, and product context. Tools: • check_product_trust — inspect one Amazon, Walmart,
Detect and redact PII, PHI, PCI and secrets — SSNs, credit cards, passports, API keys and cloud credentials — in text and in local files, using the Strac DLP API. Five tools: redact_text, detect_sensitive_data, detect_fi
